Chain of interlocking oval links

Build a chain of oval (stadium) wire links that hook through each other, as one link mesh instanced by glTF nodes at alternating 90 degree angles. Use it for props, rigging and anchors.

Limits to consider

Links are rigid and straight in a line; there is no physics or sag. Contact is only avoided geometrically when end_radius exceeds twice the wire radius plus the clearance (checked). No texture coordinates.
